Delicate in appearance but durable in its material, this Hario Lien Necklace is composed of two interlocking glass circles, one smooth and the other textured to resemble drops of water. The necklace is handmade in Japan by skilled artisans through a process that involves melting glass with a torch. Once the glass is in a molten state, it is formed by blowing and shaping with tools and hand movements. The Lien Necklace is produced by Hario, a Japanese company founded in 1921 that was known for producing glass coffeemakers and science instruments before creating jewelry. The brand has its own factory in Japan, which is the only place in the country that produces heatproof glass. This durable material has a strong resistance to temperature change and excellent durability against chemicals and shock. The Hario Lien Glass Necklace measures 25”l.
